Defcon duo: how-to shut off a pacemaker, almost get free rides on the T
Defcon already delivered by exposing California's FasTrak toll system for the security hole that it is, but that's not nearly all that's emerging from the Las Vegas exploitation conference. For starters, a plethora of medical device security researchers have purportedly figured out a way to wirelessly control pacemakers, theoretically allowing those with the proper equipment to "induce the test mode, drain the device battery and turn off therapies." Of course, it's not (quite) as simple as just buzzing a remote and putting someone six feet under, but it's a threat worth paying attention to. In related news, a trio of MIT students who were scheduled to give a speech on how to hack CharlieCards to get free rides on Boston's T subway were stifled by a temporary restraining order that the Massachusetts Bay Transit Authority snagged just before the expo. Don't lie, you're intrigued -- hit up the links below for all the nitty-gritty.Update: MIT published the Defcon presentation in a PDF.Read - Pacemaker hackRead - Massachusetts Bay Transit Authority sues MIT hackersRead - Restraining order on said hackers
Osaka University scientists create world's first optical pacemaker
Around 1.5 years ago, we got wind of researchers in the UK working up a battery-free pacemaker. Fast forward to now, and we've got yet another breakthrough in the field. Purportedly, a crew of Osaka University scientists have created the "world's first optical pacemaker," and in an article published in Optics Express, the team details how "powerful, but very short, laser pulses can help control the beating of heart muscle cells." In theory, this discovery provides the means for dictating said cells within a controlled setting, which could help researchers "better understand the mechanism of heart muscle contraction." As amazing as we're sure this is to the science world, throwing "lasers" and "heart" into the same sentence just doesn't elicit warm / fuzzy feelings.[Via Primidi]
Researchers warn of hacking risks to heart devices
While it should hardly come as a surprise given the near constant stream of hacking fears we hear about these days, researchers are now warning about a possible vulnerability to an especially important bit of technology: medical devices that control the human heart. As The Wall Street Journal reports, the concerns are mostly centered around so-called "programmers," which are devices used to wirelessly communicate with the implanted defibrillator or pacemaker. Those devices are obviously only sold directly to physicians by a select group of companies but, as the researchers warn, it is at least conceivable that hackers could transmit the same radio signals using another device, allowing them to shut down the defibrillator or deliver a shock, or possibly even obtain a patient's medical information. The researchers are quick to point out, however, that this is "theoretical risk, not an actual risk," and they're not recommending that anyone consider deferring an implantation or removing a defibrillator.

iPods won't crash your pacemaker says the FDA
It turns out that 17-year-olds probably aren't that good at studying electrical interference -- and its effect on pacemakers -- created by iPods. Unlike the data presented to the Heart Rhythm Society last year by a high-school student, which demonstrated the music player's ability to interfere with heart-regulating devices, the FDA now says that the gadgets are completely safe for use. Researchers measured magnetic fields produced by four different models of Apple's ubiquitous device, and found no reason why your grandmother can't keep jamming to her South of Heaven reissue. Said FDA researcher Howard Bassen, "Based on the observations of our in-vitro study we conclude that no interference effects can occur in pacemakers exposed to the iPods we tested." We hope the FDA will follow this up with a definitive study on the effects of boomboxes on hip implants.
Hands-on with the Pacemaker DJ system
We had a chance to get up close and personal with Swedish startup Tonium's portable DJ unit and paw this 120GB-storing mobile mixing and more device. Comparable in size to the PSP (a smidge smaller), the Pacemaker's integrated crossfader and multifunction touchpad at first blush provide a surprisingly intuitive way to control your mix. We're not gonna lie -- we kinda wish the touchpad worked more like a Kaoss pad than like ye olde iPod scroll wheel, but all the same it's pretty fun to get some pitch bending on with a device that fits in one hand. Also let's be honest, you're probably not gonna become the hottest thing in Ibiza with this thing, but at $700 it's a relatively low-cost convenient practice setup for DJs on the road or an attractive option for aspiring amateurs. Be sure to peep yourself some video after the break.%Gallery-12859%
Pacemaker DJing system gets demonstrated on video
Just months after catching wind of the Pacemaker handheld DJ system, the (lucky) folks over at Digital-Lifestyles managed to get their hands on a prototype unit and spend a few quality moments perusing its features. Interestingly, their unit did indeed sport a color display, but still retained the 120GB hard drive that was previously expected. 'Course, you're already well aware of what this thing can potentially do for you, so without further ado, be sure and check out the hands-on videos waiting after the break.Update: Aaaand we have a price. €520, about $700 US, shipping in December.

Pacemaker study leads to rash of "Granny's iPod" jokes
Many high school students are happy to get science projects done quietly, without attracting the attention of, say, the Associated Press. Not Jay Thaker. His research shows that an iPod held 2 inches from the chest can disrupt pacemaker function in some patients, which has caused a torrent of media furor over this previously unstudied and unquantified risk.Here at TUAW we don't give medical advice [You got that right. -Ed.] and we don't like to point out when big media stories about Apple products are silly, disproportionate or plain goofy... well, actually we do like to point that out. With all due respect to those who might be directly affected by this discovery, some points to consider: The study only examined iPods, no other portable media players (HD or flash-based) and so far I haven't found anything that says exactly what type of iPod was used. Is it the Shuffle that's causing skipped beats? What happens if I use a Sandisk player or a Zune? We need a control group... what about a vintage Sony Walkman? This isn't the first time we've been told portable electronic devices and pacemakers don't mix. Ten years ago, the first reports of cellphone interference came out. Users were (prudently) told to keep phones at least 6 inches from their chests, and the fuss blew over. One of the study's noted concerns was that the presence of an iPod could cause a physician to misread pacemaker telemetry during an exam. I'm not an expert, but are there any doctors that are in the habit of letting patients listen to their iPods during physical exams? Most of the time, one of you is naked, and hopefully it's not the doctor. As some of the study authors have noted, there's a reason this hasn't been a big issue: the overlap of "iPod owners" and "pacemaker patients" has not been a substantial population. All kidding aside, I look forward to seeing this study expanded to other portable electronic devices; the safety of all of them (not just the iPod) for pacemaker or other medical appliance users is worth checking. It's clear who the real losers are in this situation: the folks who, only a few days ago, introduced a new portable music player aimed at the DJ market: the Pacemaker. Ooch, that's gonna leave a mark.Thanks to everyone who sent this in.
iPods now linked to pacemaker malfunction?
What's a 17 year old doing presenting a study before a gathering of heart specialists? Why, drawing the connection between iPods and heart implants, of course. According to student Jay Thaker, the findings of his study showed that of 100 installed pacemakers, electrical interference was detected 50% of the time when an iPod was held at a distance of 2-inches from the chest for 5-10 seconds. We'd really liked to have been there to see him try and pitch this study of his to the variety of seniors with heart problems who participated (they averaged 77 years of age), but don't get alarmed, we have a feeling your grandparents -- who've probably never even heard of that newfangled iPoddie doohickie -- won't find out first hand whether this is the real deal.[Thanks to everyone who sent this in, photo via Rositress]
The Pacemaker: 'world's first' pocket-size pro DJ system
Watch out NuMark, 'cause there's about to be a new product on the scene to challenge your iDJ line of mixers -- and not only does this one rock 120GB of internal storage to obviate the need for a pair of iPods, it's actually small enough to fit in your pocket. The upcoming Pacemaker from European start-up Tonicum -- set to be unveiled tomorrow -- promises to contain all the necessary features for bringing your mixing skills on the road, including a crossfader, dual 3.5-millimeter stereo jacks, direct-to-hard drive recording, and a multifunction touchpad for adjusting bend and pitch, among others. No bells or whistles like an FM tuner or color screen on this patent-pending player, but with both Mac and Windows support, we have a feeling that the Pacemaker is going to develop a small but dedicated following.

Battery-free pacemaker on the horizon
Having one surgery is plenty, and having some foreign object implanted in your being is really pushing things, but knowing you're going to be under the knife every ten years or so to get a new battery is just absurd. Thankfully, a group of researchers in the UK feel the same way, and are well on their way to developing a battery-free pacemaker. Reportedly, the device would use a microgenerator producing electricity every time the patient moves, effectively eliminating the need for an internal battery. The cost of the £1 million ($1.96 million) project is being shared by the Department of Trade and Industry and private companies, one being Zarlink Semiconductor who has a large role in the device's development. Other teams around the globe are also seeking to create such a unit, with ideas spanning from tiny generators that receive power from heat right onto "biological pacemakers" that would correct heart problems without the need for a mechanical device. While there's no estimate as to when these gizmos will even hit the testing and approval phase, it seems that things are moving along quite well, but we have to stop and wonder how well a pacemaker powered by motion will function when you, well, cease moving.[Via MedGadget]
